  • Publication number: 20120023943
    Abstract: The present invention provides an organic Rankine cycle energy recovery system comprising features which provide for fire suppression and/or ignition suppression in the event of an unintentional release of a flammable component of the system, for example a flammable working fluid such as cyclopentane, into a part of the of the system in which the prevailing temperature is higher than the autoignition temperature of the flammable component. In one embodiment, and the organic Rankine cycle energy recovery system comprises an inert gas source disposed upstream of a hydrocarbon evaporator and configured to purge the hydrocarbon evaporator with an inert gas on detection of a leak thereby.

  • Publication number: 20120017597
    Abstract: A hybrid power generation system includes a gas turbine engine system and a supercritical rankine cycle system. The gas turbine engine system includes a first compressor, an intercooler, and a second compressor. A first compressor is configured to compress an inlet airflow to produce a first outlet airflow at a first pressure. An intercooler is coupled to the first compressor and configured to cool the first outlet airflow exiting the first compressor to produce a second outlet airflow. A second compressor is coupled to the intercooler and configured to compress the second outlet airflow exiting the intercooler to produce a third outlet airflow at a second pressure. The supercritical rankine cycle system is coupled to the gas turbine engine system.

  • Publication number: 20120000201
    Abstract: A system and method are provided for using the thermal mass of an ORC, the working fluid, the oil loop, the cooling fluid loop and all components, to provide additional transient power to an electrical grid. A pre-heater transfers heat from the cooling fluid to a low temperature (LT) ORC loop working fluid. A LT ORC loop expander generates transient power to support stabilization of the electrical grid. A heat exchanger transfers heat from the thermal oil to a high temperature (HT) ORC loop working fluid. A HT ORC loop expander generates transient power to support stabilization of the electrical grid.

  • Publication number: 20120000200
    Abstract: In one embodiment, a system includes a valve system switchable between a waste heat recovery position configured to direct incoming exhaust gas through an interior volume of an exhaust section of an engine and a bypass position configured to direct the incoming exhaust gas through a bypass duct to bypass a heat recovery boiler disposed within the interior volume. The system also includes an inert gas purging system configured to inject an inert gas into the interior volume to displace residual exhaust gas from the interior volume.

  • Publication number: 20110308252
    Abstract: A pressure sensor measures an organic Rankine cycle (ORC) working fluid pressure in front of a radial inflow turbine, while a temperature sensor measures an ORC working fluid temperature in front of the radial inflow turbine. A controller responsive to algorithmic software determines a superheated temperature of the working fluid in front of the radial inflow turbine based on the measured working fluid pressure and the measured working fluid temperature. The controller then manipulates the speed of a working fluid pump, the pitch of turbine variable inlet guide vanes when present, and combinations thereof, in response to the determined superheated temperature to maintain the superheated temperature of the ORC working fluid in front of the radial inflow turbine close to a predefined set point. The superheated temperature can thus be maintained in the absence of sensors other than pressure and temperature sensors.

  • Publication number: 20110203278
    Abstract: A waste heat recovery plant control system includes a programmable controller configured to generate expander speed control signals, expander inlet guide vane pitch control signals, fan speed control signals, pump speed control signals, and valve position control signals in response to an algorithmic optimization software to substantially maximize power output or efficiency of a waste heat recovery plant based on organic Rankine cycles, during mismatching temperature levels of external heat source(s), during changing heat loads coming from the heat sources, and during changing ambient conditions and working fluid properties. The waste heat recovery plant control system substantially maximizes power output or efficiency of the waste heat recovery plant during changing/mismatching heat loads coming from the external heat source(s) such as the changing amount of heat coming along with engine jacket water and its corresponding exhaust in response to changing engine power.
